Mary Chilton is said to be the first woman to step ashore from the Mayflower in 1620. At thirteen Mary Chilton was thus left an orphan at Plymouth. No record reveals with whom she spent the next few years, but perhaps for at least a part of the time she was member of either the Alden or the Standish household; in the 1623 land division "Marie" Chilton received her share (undoubtedlly three acres—one for herself and one for each parent) between the shares of John Alden and Myles Standish. By the time of the cattle division of May 1627, Mary had married John Winslow, and the couple were included with John Shaw's group.
